我有以下karma.conf.js文件,我还有一个名为的测试文件example.spec.js,它位于app/compontents/example/example.spec.js我试图导入我的Example.js file

import Example from 'app/components/Example/Example.jsx';

describe('Example Component', function() {

});

但是我得到了以下错误Error: Cannot find module "app/components/Example/Example.jsx"我尝试了许多不同的想法,例如./Example.jsx, ./Examplecomponents/Example/Example.jsx但每次我得到相同的错误。

var webpack = require('webpack');

module.exports = function(config) {
 config.set({

如果你想使用这样的导入,你需要设置一个resolve.alias。演示:

resolve: {
    alias: {
        app: path.join(__dirname, 'app')
    }
}
